It’s well established if the US wants to they can find them and crypto can be traced.
Same question though how are they paying for the domain, assuming this is on the plaintiff to trace
Well clearly that’s false? Not all crypto transactions are traceable for example. And since they haven’t found them, that seems to disprove your statement doesn’t it?
What does "finding them" even means in this context? There are many hacker organizations located in Russia that are much worse than Anna's Archive. From my understanding those also operate websites / platforms to offer services.
